Lights out!

[jedi31]

Ever since I started dosing Prodibio Bio digest and Bioptim my tank has gone down hill. I have stoped dosing for three weeks already and things are still not getting better. Once I starting dosing I had some STN and cyano. Well after a few weeks of no dosing the corals are looking somewhat better but I still have Cyano and it's getting worse. I needed to feed the fish more because after the dosing I had 0 nitrates and .01 phosphates on my hanna. The Phosphates are at 0.04 right now and Cyano seems to be getting worse. Urhhhhh....... I was thinking about turing out the light for 3 days (MH) and do some water changes during those days. Will my SPS suffer a lot w/o no light for three days? Has anybody done this with success?
Here are thee rest of my Pars

Alk- 7.7 - 8.0
Cal 440
Mag 1200
PH 8.2-8.3
Nitrates - .02
Phospahtes- .04
Salinity 1.025 = 1.026

my best bet is that your tank is suffering right now and taking that measure will inflict more damage, if cyano bothers you just siphon it out, dont use any chemicals for now like (chemiclean) good lcuk
